As optional technical scheme, described backlight comprises: the second fluorescent tube drive plate that contiguous described the 4th side is provided with, the described second fluorescent tube drive plate be fixed on the described base plate and with the described reflector plate of described base plate clamping.
As optional technical scheme, described base plate has a plurality of reference columns, and described reflector plate has the locating hole that a plurality of and described reference column cooperates.
As optional technical scheme, described base plate is a metal base plate, and described projection is the metal tabs.
As optional technical scheme, described base plate has two fins that are respectively adjacent to described first side and the setting of described second side, and described a plurality of projectioies are separately positioned on described two fins.
Another object of the present invention provides a kind of display unit, and it comprises above-mentioned a kind of backlight and a display panels, and described display panels is positioned on the described backlight.
Compared with prior art, benefit of the present invention is, and is need not double faced adhesive tape between reflector plate and the base plate bonding, makes up and reprocesses easily.

[specific embodiment]
Fig. 1 illustrates the schematic top plan view of the backlight base plate of first kind of embodiment of the present invention, and Fig. 2 illustrates along the side-looking generalized section of A-A line among Fig. 1.As depicted in figs. 1 and 2, the backlight base plate 10 of present embodiment has the first relative side 111 and second side 112, relative the 3rd side 113 and the 4th side 114, and described base plate 10 has a plurality of projectioies 12 that described first side 111 and second side 112 are provided with that are respectively adjacent to.The backlight base plate 10 of present embodiment also has a plurality of circular reference columns 15, and this is not necessarily in other embodiments.The backlight base plate 10 of present embodiment has two fins 19 that are respectively adjacent to described first side 111 and 112 settings of described second side, and described a plurality of protruding 12 are separately positioned on described two fins 19, and fin 19 not necessarily in other embodiments.Base plate 10 can be metal (for example aluminium alloy) base plate, and described protruding 12 can be the metal tabs that stamps out from base plate 10.
Fig. 3 illustrates the schematic top plan view of the backlight reflector plate of first kind of embodiment of the present invention, and Fig. 4 illustrates the base plate of first kind of embodiment of the present invention and the schematic top plan view after the reflector plate combination.As shown in Figure 3 and Figure 4, the backlight of present embodiment comprises the reflector plate 20 that covers on the described base plate 10, and described emission sheet 20 has described protruding 12 open-works 22 that are provided with of a plurality of correspondences; Described reflector plate also has the locating hole 25 that a plurality of and described reference column cooperates.
Fig. 5 illustrates the schematic top plan view of the backlight of first kind of embodiment of the present invention.As shown in Figure 5, the backlight of present embodiment also comprises first fluorescent tube drive plate 31 of contiguous described the 3rd side 113 settings and the second fluorescent tube drive plate 32 that contiguous described the 4th side 114 is provided with, and the two ends of a plurality of straight light tubes 51 are separately positioned on the first fluorescent tube drive plate 31 and the second fluorescent tube drive plate 32.The described first fluorescent tube drive plate 31 and the second fluorescent tube drive plate 32 be fixed on the described base plate 10 by screw or card and structure and with the described reflector plate 20 of described base plate 10 clampings.The backlight of present embodiment also comprises a plurality of lamp tube fixing piece 41, described lamp tube fixing piece 41 be fixed on the described base plate 10 and with the described reflector plate 20 of described base plate 10 clampings.Fig. 6 illustrates along the side-looking generalized section of B-B line among Fig. 5.As shown in Figure 6, lamp tube fixing piece 41 comprises tube clamping portion 411, lamp tube fixing piece 41 is blocked and trip 412 and compressing tablet 413 on base plate 10, and compressing tablet 413 has clamped reflector plate 20 with base plate 10.Lamp tube fixing piece is applied in the backlight widely, and its structure is varied, can use the lamp tube fixing piece of arbitrary structures in other embodiments, as long as it can clamp reflector plate with base plate.In the backlight of present embodiment, reflector plate 20 is fixed by projection 12 in first side 111 and second side 112, fixing in the 3rd side 113 and the 4th side 114 by the first fluorescent tube drive plate 31 and the second fluorescent tube drive plate 32, fixed by lamp tube fixing piece 41 at the middle part, so can not re-use double faced adhesive tape between reflector plate 20 and the base plate 10 and fix.
